摘要：

An improved unusual finite element method is studied herein for a second-order linear scalar differential equation including a zero-order term. The method consists in subtracting from the standard Galerkin method a mesh dependent term suggested by static condensation of the bubbles. Based on this idea, a neu stabilized parameter is constructed, which improves accuracy of the solution, Several numerical tests attest the efficiency of the present method and an error analysis is performed.
